Resonance in Ploče Harbor (Adriatic Sea)
نویسندگان
چکیده
In this paper, we extract and validate high-frequency oscillations in the port of Ploče, based on sea level data from one year (March 2002-March 2003) measured at a tide gauge in the harbor. Frequency was analyzed by applying stationary (spectral) and non-stationary (wavelet and filtering) analyses of the data to extract temporal characteristics of the fundamental seiches with a period of 30 min. Seiches are pertinent throughout the year, but their maximum amplitude doubles (up to 25 cm) during the summer. Modeling studies showed that seiches are primarily a result of incoming waves from the open sea, generated by resonant coupling with air pressure traveling waves. In contrast, direct wind forcing has a minor influence on seiche generation. Seiches endanger ferries and small moored boats as well as large cargo ships in harbors where strong currents (greater than 50 cm s-1) appear during extreme events.

The abundance, distribution and speciation of mercury in waters and sediments of the Adriatic Sea – a review
This review focuses on mercury speciation in the Adriatic Sea, a marginal sea of the Mediterranean, which represents its distinct biogeochemical subunit due to anthropogenic mercury loadings. The current knowledge about mercury cycling in the Adriatic is presented through an overview of the state of the art of research in this area: temporal and spatial distributions and occurrence of mercury s...

A modelling system for the Adriatic Sea has been built within the framework of the Mediterranean Forecasting System Pilot Project. The modelling system consists of a hierarchy of three numerical models (whole Mediterranean Sea, whole Adriatic Sea, Northern Adriatic Basin) coupled among each other by simple one-way, off-line nesting techniques, to downscale the larger scale flow field to highly ...
متن کاملIndications of Climate Regime shifts in the Middle Adriatic Sea
The Adriatic Sea, as adjacent sea of the greater Mediterranean Sea, is under direct influence of atmospheric processes and their variability. Cold deep water formed under strong winter outbursts of Bura wind in the Northern Adriatic plays crucial role in the overall Adriatic circulation. Interannual variability of temperature and salinity in the Adriatic Sea is firstly interplay of Northern Adr...
متن کاملEstimation of the Adriatic sea water turnover time using fallout 90 Sr as a radioactive tracer
Systematic, long term measurements, starting in 1963, of Sr activity concentrations in sea water have been performed at four locations (cities of Rovinj, Rijeka, Split and Dubrovnik) along the Croatian coast of the Adriatic sea. In addition, fallout samples were collected in the city of Zadar. Sr activity concentrations are in good correlation with the fallout activity, the coefficient of corre...
